1. What is the scientific name for the kneecap?
- A. Patella
- B. Femur
- C. Tibia
- D. Fibula
Correct answer: A
Rationale: The patella, commonly known as the kneecap, is a small, flat, triangular bone that sits at the front of the knee joint. It protects the joint from impact and helps to transmit force from the quadriceps muscle to the tibia (shinbone).
2. Which property of a wave determines its energy?
- A. Wavelength
- B. Amplitude
- C. Frequency
- D. Velocity
Correct answer: b
Rationale: Amplitude is directly related to the energy carried by a wave - higher amplitudes correspond to higher energy waves.
3. Which of the following is NOT a method for preventing healthcare-associated infections (HAIs)?
- A. Handwashing with soap and water
- B. Proper use of personal protective equipment (PPE)
- C. Reusing sterile medical devices
- D. Reusing sterile medical devices
Correct answer: D
Rationale: Rationale: Reusing sterile medical devices is not a method for preventing healthcare-associated infections (HAIs). In fact, reusing sterile medical devices can increase the risk of infections due to inadequate sterilization or potential damage to the devices during the reprocessing process. Proper sterilization and disposal of single-use medical devices are essential in preventing the transmission of infections in healthcare settings. A) Handwashing with soap and water is a crucial method for preventing HAIs as it helps to remove and reduce the number of pathogens on the hands of healthcare workers, preventing the spread of infections. B) Proper use of personal protective equipment (PPE) such as gloves, gowns, masks, and eye protection is important in preventing the transmission of infections between patients and healthcare workers. C) Reusing sterile medical devices is not a recommended practice as it can lead to the transmission of infections if the devices are not adequately ster
4. Which type of transport allows for the movement of large molecules, such as proteins and polysaccharides, across the cell membrane?
- A. Endocytosis
- B. Exocytosis
- C. Active transport
- D. Facilitated diffusion
Correct answer: A
Rationale: Rationale: A) Endocytosis is the process by which cells engulf large molecules or particles by wrapping the cell membrane around them to form a vesicle that is brought into the cell. This mechanism allows for the movement of large molecules, such as proteins and polysaccharides, across the cell membrane. B) Exocytosis is the opposite process of endocytosis, where cells release large molecules or particles by fusing vesicles with the cell membrane to expel their contents out of the cell. C) Active transport is a process that requires energy to move molecules across the cell membrane against their concentration gradient. While active transport can move large molecules, it is not specifically designed for the transport of proteins and polysaccharides. D) Facilitated diffusion is a type of passive transport that involves the movement of molecules across the cell membrane with the help of transport proteins. While facilitated diffusion can assist in the movement of
5. Which part of the brain is responsible for regulating heart rate, breathing, and swallowing?
- A. Cerebrum
- B. Cerebellum
- C. Medulla oblongata
- D. Thalamus
Correct answer: C
Rationale: The correct answer is C: Medulla oblongata. The medulla oblongata is located at the base of the brainstem and is responsible for regulating essential functions such as heart rate, breathing, and swallowing. It contains vital control centers for these automatic processes, making it a critical part of the brain for maintaining life. The cerebrum is primarily involved in higher brain functions such as thinking and voluntary movement, while the cerebellum helps with coordination and balance. The thalamus acts as a relay station for sensory information. Therefore, the medulla oblongata is the most appropriate choice for regulating these basic physiological functions.
6. Which element is used in fluorescent lamps and emits ultraviolet light when excited?
- A. Mercury
- B. Neon
- C. Argon
- D. Krypton
Correct answer: A
Rationale: Mercury vapor in fluorescent lamps generates UV light that excites phosphors on the lamp's inner surface, producing visible light.
